Clean up sql directory after production sync
- Remove 27 completed one-off migration scripts - Remove old backup file (dev-backup-20251120) - Remove completed shell scripts for prod import/export - Archive migration_phase1-4 directories and documentation - Keep only view_consolidation.sql as active script All migrations have been applied to production. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

-- ROLLBACK: Phase 3 Migration
|
||||
-- =====================================================
|
||||
-- Date: 2025-11-10
|
||||
-- Purpose: Rollback Phase 3 migration (Network Devices)
|
||||
-- USE WITH CAUTION: This will delete migrated data
|
||||
-- =====================================================
|

--
|
||||
-- IMPORTANT: READ BEFORE RUNNING
|
||||
-- =====================================================
|
||||
-- 1. This script removes all network devices from machines table
|
||||
-- 2. Old tables (servers, switches, cameras) must still exist
|
||||
-- 3. Only run if migration failed or issues found
|
||||
-- 4. Backup database before rollback!
|
||||
-- 5. Cannot rollback if old tables were dropped
